hiya....do you mean that your existing ones are welded to the pipes??
anyways..a jubilee is not a strong enough clamp as they are only soft alloy...you need a stainless clamp.....why not give the ex-CCC guy a pm...Simon Cope..to buy a couple, they should not cost too much. his new company is called POWERTECH 01253 891087
OK??/ Happy modding!!!!
